<![CDATA[Penggunaan perangkat lunak bajakan masih dianggap biasa di kalangan masyarakat. Penggunaan perangkat lunak bajakan bisa dikurangi dengan jalan berpindah ke penggunaan perangkat lunak Open Source. Penggunaan Open Source juga bermanfaat sebagai pendorong perbaikan karakter masyarakat secara luas. Karakter yang terkait erat dan hal ini adalah sifat jujur dan menghargai nilai-nilai yang berkembang di masyarakat. Perangkat lunak open source belum banyak digunakan di SMA Negeri 12 Semarang. Keberadaan laboratorium komputer di sekolah tersebut memungkinkan untuk memperkenalkan Open Source Sofware bagi guru dan staf administrasi. Kegiatan pengabdian dilakukan dengan mengadakan sosialisasi perangkat lunak Open Source di SMA N 12 Semarang. Tahap selanjutnya adalah melakukan instalasi, mengadakan pelatihan dan praktik. Kegiatan pengabdian kepada masyarakat ini telah berhasil melakukan sosialisasi perangkat lunak open source di SMA N 12 Semarang. Para peserta juga telah berhasil menggunakan peangkat luak tersebut.]]>

<![CDATA[The current topic that is interesting as a solution of the impact of public service improvement toward vehicle is License Plate Recognition (LPR), but it still needs to develop the research of LPR method. Some of the previous researchs showed that K-Nearest Neighbour (KNN) succeed in car license plate recognition. The Objectives of this research was to determine the implementation and accuracy of Otsu Method toward license plate recognition. The method of this research was Otsu method to extract the characteristics and image of the plate into binary image and KNN as recognition classification method of each character. The development of the license plate recognition program by using Otsu method and classification of KNN is following the steps of pattern recognition, such as input and sensing, pre-processing, extraction feature Otsu method binary, segmentation, KNN classification method and post-processing by calculating the level of accuracy. The study showed that this program can recognize by 82% from 100 test plate with 93,75% of number recognition accuracy and 91,92% of letter recognition accuracy. ]]>

<![CDATA[Issue handling of inadvertence situations in the decision-making process of recruiting new employees at PT. Warta Media Nusantara that use criteria value of interviews, field test, a psychological test and medical check-up requires Multi Attribute Decision Making (MADM) as an auxiliary method of decision-making on the prospective eligible employee to be accepted in the company. There are various MADM methods, such as Simple Additive Weighting (SAW) method and Weighted Product (WP) method. Both of these methods are known as the most common method used in handling MADM issues, so in this study both methods are applied to the DSS and analyzed the differences in terms of obtained results and the execution time required for each method. The results of the study of the application of SAW and WP methods in the recruitment of new employees DSS there are some differences in the results of the candidates rank order and the differences in execution time of each method. The differences in rank order of these methods are due to the effects of alternative values, weighting criteria, and the calculation method. WP method is able to provide more rigorous result than SAW method, while the difference in execution time of SAW and WP methods explains that the execution time of SAW method relatively quick because SAW calculation method has a simpler process than the process of WP calculation methods ]]>

<![CDATA[Proses pembelajaran IPA yang memadukan konsep fisika, kimia, dan biologi lebih berpotensi untuk mengembangkan pengalaman dan kompetensi peserta didik memahami alam sekitar. Pembelajaran IPA di SMP Negeri 1 Pucakwangi kurang optimal dalam pemanfaatan lingkungan dan penggunaan media pembelajaran maka perlu dikembangkan CD pembelajaran berbasis kearifan lokal. Tujuan penelitian ini adalah untuk mengembangkan media pembelajaran yang layak digunakan berupa CD pembelajaran berbasis kearifan lokal. Penelitian dilakukan di SMP Negeri 1 Pucakwangi dengan siswa kelas VIII B, VIII F dan VIII G sebagai subyek penelitian. Penelitian dilakukan dengan motode Research and Development (R & D) Four-D Model. Hasil penelitian pakar menunjukkan CD pembelajaran berbasis kearifan lokal valid dan sangat layak digunakan. Tanggapan siswa terhadap pemahaman tentang kearifan lokal mengalami peningkatan sebesar 94,19%. CD pembelajaran berbasis kearifan lokal mampu meningkatkan minat dan hasil belajar siswa. Hasil penelitian berdasarkan uji-t menunjukan terjadi perbedaan secara signifikan antara sebelum dan sesudah pembelajaran menggunakan CD pembelajaran berbasis kearifan lokal. Dengan demikian dapat disimpulkan bahwa CD pembelajaran berbasis kearifan lokal layak digunakan pada proses pembelajaran, serta dapat meningkatkan kecintaan terhadap budaya lokal yang ada di lingkungan sekitar. Science learning process that combines the concepts of physics, chemistry, and biology is potential to develop the experience and competence of the learners’ understanding about the nature around us. Science learning in SMP Negeri 1 Pucakwangi was inadequate in using the environment and use of instructional media, therefore it is necessary to develop local wisdom-based learning CD. This study aims to develop a viable learning medium used in the form of local wisdom-based learning CD. The research was conducted in grade VIII B, VIII F and VIII G of SMP Negeri 1 Pucakwangi as research subjects. The study was Research and Development (R&D) Four-D Model design. Validation showed that local wisdom-based learning CD is valid and very suitable as learning media. Student responses to understand the local wisdom had increased to 94.19%. Local wisdom-based learning CD can increase student’s interest in local knowledge and student learning outcomes. The results based on t-test showed that there was significant difference between the learning before and after using the local wisdom-based learning CD. It can be concluded that the local wisdom-based learning CD is effective in applying local wisdom in the learning process, and can increase student’s interest in local culture that exists in the surrounding environment. ]]>

<![CDATA[Berdasarkan Permendiknas No. 22 tahun 2006 pembelajaran IPA seharusnya dilakukan secara terpadu. Namun kenyataannya belum ada perangkat pembelajaran IPA secara terpadu dan media yang mampu memaparkan keterpaduan bidang kajian IPA. Tema mata mempelajari konsep abstrak yang membutuhkan media untuk menggambarkan konsep abstrak menjadi pengalaman konkret. Penelitian ini bertujuan menghasilkan sebuah media pembelajaran IPA terpadu yang layak dan efektif digunakan dalam pembelajaran. Metode penelitian yang digunakan adalah penelitian dan pengembangan (Research and Development). Berdasarkan validasi pakar, tanggapan guru dan siswa serta hasil evaluasi siswa, maka media interaktif layak digunakan sebagai media pembelajaran IPA terpadu tema mata. Based on the Regulation of National Education Minister (Permendiknas) Number 22 year 2006, educating science should be done integratedly. However, in fact integrated science learning equipment and media that can represent the integration of study in science field have not been provided well. The theme “eye†studies about the abstract concepts which need media to represent them into concrete experiences. This research aims to produce a feasible and effective integrated science learning media to be used in teaching- learning process. Research method used in this study is Research and Development. Based on expert validation, the teacher’s and students’ feedback and opinion, and also the result of the evaluation, it can be concluded that interactive media is feasible to be used as integrated science learning media themed “eyeâ€.  ]]>
